DESCRIPTION

· The ATmega48A/PA/88A/PA/168A/PA/328/P is a low-power, CMOS 8-bit microcontroller based on the AVR® enhanced RISC architecture.

· It achieves CPU throughput approaching one million instructions per second (MIPS) per megahertz by executing instructions in a single clock cycle.

· Optimizes power consumption versus processing speed for system designers.

FEATURES

· High Performance, Low Power AVR® 8-Bit Microcontroller Family with Advanced RISC Architecture.

· 131 Powerful Instructions with Most Single Clock Cycle Execution.

· 32 x 8 General Purpose Working Registers and Fully Static Operation.

· Up to 20 MIPS Throughput at 20MHz with On-chip 2-cycle Multiplier.

· High Endurance Non-volatile Memory Segments with In-System Self-Programmable Flash program memory, EEPROM, and Internal SRAM.

· Write/Erase Cycles: 10,000 Flash/100,000 EEPROM with Data retention of 20 years at 85°C/100 years at 25°C.

· Optional Boot Code Section with Independent Lock Bits and In-System Programming by On-chip Boot Program.

· QTouch® library support for Capacitive touch buttons, sliders, and wheels with up to 64 sense channels.

· Peripheral Features include Two 8-bit Timer/Counters and One 16-bit Timer/Counter with Separate Prescaler, Compare Mode, and Capture Mode.

APPLICATIONS

· Suitable for applications requiring low power consumption and high processing speed.

· Ideal for systems needing in-system self-programmable memory and high endurance non-volatile memory.

· Applicable in designs requiring capacitive touch sensing with QTouch® library support.

· Useful in systems that benefit from advanced timer/counter peripherals for precise timing and control.
